new set-top box

I just called up Starhub for an additional set-top box. And it costs $12 PLUS a one-time charge of $20.


Me: WHAT? I don't understand. I already have two set-top boxes at home. Why do I still have to pay for another one-time fee?

Man: Oh it's for the installation service. It's just another one-time charge.

Me: It's ANOTHER one-time charge?!

Man: It's for the transport for the technician.

Me: NO! It's okay, I don't want it anymore. It doesn't make sense.

Man: Ok we will waive it for you. It's just $12 per month.


Must I raise my voice to get my way?
